A. 1.8600 x 105 mi/s

Explanation:

The problem gives us the value of the speed of light in ft/s: v=982,080,000 ft/s

We know the conversion factor between feet and miles:

1 mi = 5280 ft

So we can apply this conversion factor to the speed of light:

v=982,080,000 ft/s \cdot \frac{1}{5280 ft/mi}=186,000 mi/s=1.86\cdot 10^5 mi/s

what are the variables in an experiment that tests the distance honey flows at different temperatures? identify the independent
soldier1979 [14.2K]

Answer:

The distance that the honey flowed would be the dependent or outcome variable and the temperature of the honey would be the independent variable.

The dependent variable is what is being measured in an experiment. You can remember it by thinking “it depends on what you’re changing.”

The independent variable in an experiment is what is being changed. You can remember this by thinking “the Independent variable is what I as the scientist change.”
